When looking at the Fastest Known Times on a trail, there's a new calendar icon.
Hovering (or clicking on mobile) on this will display the date of the member's run.
As there is often a difference between the runnability of a track in summer vs. winter conditions, this will help give you an idea of your expected times.
And yes, I have screenshotted a trail where I have the FKT on purpose 🤣
Thanks to Kirsten Fryer for this suggestion
